The Toshiba 50-inch 4K Fire TV is a high-end TV actually, with support for Dolby Vision and DTS Surround Sound. Which is going to give you a really great experience. Of course, inside this TV is Fire TV. So instead of using some terrible proprietary UI for this TV, you’re going to be able to use your favorite apps and an UI that you already know. This TV from Toshiba is a really great one, and getting a 50-inch 4K TV for under $400 is pretty incredible. Let alone one that is this good, and has Fire TV built-in.
